Some adolescents can achieve academic success and maintain well-being despite their engagement in video gaming. Social factors may play a role in their vulnerability to mental health problems.

This study examined the role of perceived peer support and childhood experiences of optimal parenting in the association between video-gaming duration and depressive symptoms in adolescents.

A sample of 1071 adolescents (mean age 13.62 years, s.d. = 0.95) completed a questionnaire on video-game usage. Their perceptions of parental care and support since childhood were assessed using the Parental Bonding Instrument, whereas their perceived peer friend support was assessed using the friend support subscale of the Multidimensional Scale of Perceived Social Support. Their depressive symptoms were measured using the depression subscale of the Depression Anxiety Stress Scales. Moderated mediation analysis was conducted to examine the associations of these variables. Family socioeconomic status and symptoms of attention-deficit hyperactivity disorder were included as covariates.

Longer durations of video gaming were associated with higher levels of depressive symptoms. The role of perceived peer support in this association was moderated by childhood experiences of optimal parenting. Specifically, the mediating role of perceived friend support was significant only for adolescents who lacked optimal parenting.

The relationship between frequent video gaming and depressive symptoms in adolescents is complex and may depend on the levels of peer and parental support. Lacking support from both parents and peers can increase adolescents’ risk of depression associated with frequent video gaming.

The association between a pregnant mother’s vitamin D status and depressive symptoms has yielded inconsistent results. It is possible that other factors play a role in this association, as depression can have multiple causes. Recognizing the significance of the husband’s participation in antenatal care, this study aimed to examine whether the husband’s involvement moderates the link between the mother’s vitamin D status and depressive symptoms during pregnancy.

A total of 2983 Chinese married pregnant women, in their 25–35 weeks of pregnancy, completed questionnaires to assess their levels of depressive symptoms and the involvement of their husbands in their antenatal care appointments. Additionally, their serum levels of vitamin D were measured.

After adjusting for maternal age, parity, and socio-economic status, the husband’s involvement in antenatal care moderated the association between maternal vitamin D status and depressive symptoms during pregnancy (β = 2.03, p = 0.035). Specifically, when their husbands were not regularly present for antenatal care appointments, mothers with suboptimal vitamin D levels experienced more depressive symptoms than those with optimal levels. However, there were no noticeable differences in depressive symptoms between vitamin D groups for mothers whose husbands attended all antenatal care appointments.

Pregnant women who have suboptimal vitamin D levels and lack support from their spouses are most vulnerable to experiencing depression. It is crucial to holistically assess the social and physiological needs of expectant mothers to reduce their risk of antenatal depression.

Growing evidence indicates an association between disordered eating and a range of mental health problems, including anxiety, depression and emotional dysregulation.

This study aimed to explore whether reducing risk factors for eating disorders, such as body dissatisfaction and low self-esteem, through school-based programmes can enhance adolescent mental health.

We searched PubMed, PsycINFO, EMBASE and Web of Science from the date of inception to 15 October 2023. Data were synthesised by using a systematic narrative synthesis framework, and formal assessments were conducted to assess the quality of the included studies.

After title/abstract screening and full-text assessment, 13 articles met the pre-specified inclusion criteria, comprising a total of 14 studies (n = 5853). Notably, three studies encompassed multiple programmes, leading to the identification of 17 eating disorder prevention programmes. Among these programmes, seven (41%) employed dissonance-based approaches. Topics covered in the programmes included psychoeducation, body acceptance, sociocultural issues, nutrition and physical activities, self-esteem and stress coping. Ten (59%) of the programmes were effective in improving adolescent mental health. Six of the 14 studies (43%) did not specify follow-up time, and quality assessments found the majority to be of either high (five studies, 36%) or fair (eight studies, 57%) quality.

The findings from the ten effective programmes consistently support the use of body acceptance strategies in improving the mental health of adolescent students. Brief interventions delivered by trained, non-licensed facilitators appear good for the sustainable implementation of in-school psychological services to support well-being among adolescents.
